Constraint Architecture of Physical AI Deployment: A Coupled Interaction Model

Physical AI deployment – autonomous systems that perceive, decide, and act in the physical world underreal consequence – is failing at the pilot-to-production boundary at non-trivial rates across multipleindustrial settings. The paper’s central contribution is the Constraint Interaction Model (CIM), which demonstrates that the four laws form a fully coupled system: every law interacts with every other, producing six pairwiseinteractions that are shown to be directionally asymmetric in four of the six cases, yielding up to twelvedistinct diagnostic signatures across the four-law space.
